Ian McKellen, Patrick Stewart on ‘X-Men: Days of Future Past’

In their new film “X-Men: Days of Future Past,” Ian McKellen and Patrick Stewart reprise their roles as Magneto and Charles Xavier, respectively. This time, they’re sharing the roles with two other actors.

In Bryan Singer’s new film, which will be released in May, Michael Fassbender returns as young Magneto, while James McAvoy is once again young Charles Xavier (both actors played the younger characters in the 2011 film “X-Men: First Class”).

Did the elder actors sync their performances with the younger ones in any way?

“No. It’s up to them to sync with us,” McKellen joked. Stewart agreed, “We came first.”

In this WSJ Video clip, McKellen and Stewart discuss playing with Fassbender and McAvoy, and whether they’ll do a future “X-Men” film after “Days of Future Past.”
